the first cable which was not working .... hm ... mist ... I associate it with my TV and my stereo. Since the cable was not working I sent it back, it was no problem and was immediately a new one. The "new" cable will now work properly, now I no longer had Prblem so. I find the cable great, but have to say that I have to compare and no other cable, but I can not imagine that that are so much better.
